Hi Harpreet,

you can try below setting in web.xml in prweb.war

Open web.xml for prweb and find these lines:

<!--
Restrict Diagnostic Data to administrative users
-->
<security-constraint>
    <web-resource-collection>
        <web-resource-name> Diagnostic Data</web-resource-name>
            <description> Serves diagnostic files generated by the JMX client
            </description>
            <url-pattern> /DiagnosticData</url-pattern>
            <http-method> GET</http-method>
            <http-method> POST</http-method>
        </web-resource-collection>
        <auth-constraint>
            <role-name> PegaDiagnosticUser</role-name>
            SMA Security
            CONFIDENTIAL  7
        </auth-constraint>
</security-constraint>

Remove or comment out the following lines from the web.xml content shown above:

<auth-constraint>
            <role-name> PegaDiagnosticUser</role-name>
            SMA Security
            CONFIDENTIAL  7
</auth-constraint>
